Answer:
3/5 c + 70 = 1650.
Step-by-step explanation:
If c is the number of calories in the cheeseburger, we can see that the entire number of calories for the meal is 3/5 c + 70 = 1650.
If we want to isolate c, we can subtract both sides by 70.
3/5 c = 1580
Answer:
(2, 13)
Step-by-step explanation:
Since they both equal y, you can equal them to each other.
8x - 3 = 2x + 9
Subtract 2x from both sides.
6x - 3 = 9
Add 3 to both sides.
6x = 12
Now divide 6 on both sides.
x = 2
Now that we have found x, we need to find y. Just plug in x to the equations.
y = 2(2) + 9
y = 4 + 9
y = 13
Now, if the next equal has the same y, then both are true.
8(2) -3 = y
16-3=y
13 = y
So therefor, both x and y are true.
